Study "_Tools\CopyFiles.bat" and "CopyFilesBack.bat"
What they do: CopyFiles.bat moves all the 72b videos to Output folder. CopyFilesBack.bat copy all the 72b videos back to game folder after conversion is finished + move the files in Output folder to last DVD. Setup.exe will copy them to game folder after installation. I didn't want to use 2 archives just for this (because you will get weird % in installation with 2 diskspan archives)
